Hola!

I'm searching for an option which allow to avoid overlapping of sketches over the solids, see the attached picture, where the sketch is drawed on the floor level and the solid parts are situated over the floor level. The ''overlapping" picture is a top view and "overlapping 1" is the isometric view of the same solid parts. Does anyone know about that option? And, if this option doesn't exist, does anyone know some way to achieve that?overlapping

overlapping 1

Thank you in advance.
